<h3>Notes:</h3><br>

<p><p style="direction:ltr;"><font color="#000000">Let's use a real example to see TCP's performance. This is over a 1Gb/s link with varying RTT and loss rate. On local area networks (RTT is about 1ms) and the loss rate is low (0.01%), TCP can work well. And as loss rate increases, TCP's throughput decreases.</font></p>
<p style="direction:ltr;"><font color="#000000"></font></p>
<p style="direction:ltr;"><font color="#000000">Now let's see what happens if the RTT becomes larger. TCP's performance drops sharply, even at a low loss rate.</font></p>
